NEXT.JS TYPEGEN TRAP FIXED, TURBOREPO CUTS TEST WALL CLOCK TIME

Next.js v16.3.0-canary.36 ships a critical CLI fix that prevents silent typegen failures from masquerading as successful builds.

The typegen command had a rejection-handling gap that let config errors slip through with exit code 0, leaving developers staring at TypeScript errors with no hint of the actual problem [1]. This lands in the latest canary alongside Turbopack improvements to the analyzer [2]. Over in Turborepo, the team is aggressively trimming integration test bloat by skipping installs for metadata-only tests and committing stable fixture lockfiles [3], cutting wall-clock time without sacrificing coverage. They're also adding final hash contract snapshots to guard against accidental cache drift [4]. Windows users will see real graceful shutdown now, not force kills that left dev servers hanging [5]. The Workflow team hardened their new trace viewer with a loading skeleton that mirrors the real layout to eliminate shift jank [6], and added label-gated CI for reproducing event-log race conditions [7].

Action items

→ Test Next.js v16.3.0-canary.36 in your monorepo if you use the typegen CLI vercel/next.js [plan]
→ Monitor Turborepo's final hash contract test suite for any local hash instability vercel/turborepo [monitor]
→ Upgrade Turborepo if you're on Windows and run dev servers through turbo vercel/turborepo [plan]
